A poly(glycidylmethacrylate-divinylbenzene)-based anion exchanger for ion chromatography

Studies on Preparation, Characterization and Application of Porous Functionalized Glycidyl Methacrylate-Based Microspheres

“…Polymeric microspheres derived from glycidyl methacrylate (GMA) are very attractive as a useful material with a broad range of applications. Copolymers are widely used as ion exchangers [16][17][18][19][20], macromolecular supports for enzyme immobilization [21][22][23] or catalysts [24], column packings for HPLC [10][11][12]25], and dye remover [26,27]. Microspheres based on GMA are also widely applied in bioseparation [28,29], cell isolation [30], nucleic acid and protein purification and immunoassay [31][32][33][34].…”

A strong anion exchanger of poly(glycidyl methacrylate‐divinylbenzene) substrate functionalized with cationic quaternary ammonium monomer

“…The residual carboxylate groups onto the surface of GMA‐DVB particles produced in the hydrolysis process may also be responsible for this, which will lead to the electrostatic exclusion of anions. Such treatment has been proved to improve the hydrophilicity of anion exchangers in our previous reports [11, 14].…”

“…GMA‐DVB microspheres with 55% crosslinking degree, prepared as previously described [14], were firstly hydrolyzed at 65°C in 0.1 M H 2 SO 4 aqueous solution for 2 h. The microspheres were dried at 60°C overnight to obtain hydrolyzed GMA‐DVB (termed as GH). 3.0 g GH, 0.05 g potassium persulfate, and a given amount of MAPTAC were well suspended in 60 ml ACN‐water (v/v = 1/1) in a 100 ml flask.…”

“…The pendant double bonds associated with GMA‐DVB have been proved to show active properties [13], which can be initiated to be surface polymerized with vinyl‐based functional monomers. In our previous report [14], an anion exchanger was described by grafting dimethylaminoethyl methacrylate methylchloride (DMC) onto GMA‐DVB particles in such a way. It exhibited good separation ability towards common inorganic anions.…”
